ZSR SERIES 2.85 TO 12 VOLT FIXED POSITIVE LOCAL VOLTAGE REGULATOR DEVICE DESCRIPTION FEATURES The ZSR Series three terminal fixed positive voltage • Small outline SO8 and SOT223 package regulators feature internal circuit current limit and • thermal shutdown making the devices difficult to TO92 package destroy. The circuit design allows creation of any • 2.85 to 12 Volt custom voltage in the range 2.85 to 12 volts. The • Output current up to 200mA devices are available in a small outline surface mount • Tight initial tolerance package, ideal for applications where space saving is important, as well as through hole TO92 style • Low quiescent current packaging. The devices are suited to local voltage • -55 to 125°C temperature range regulation applications, where problems could be • No external components encountered with distributed single source regulation, a s w e l l a s m ore ge ner a l vol t age r e g u l a t i o n • Internal thermal shutdown applications. • Internal short circuit current limit The ZSR Series show performance characteristics VOLTAGE RANGE superior to other local voltage regulators. The initial output voltage is maintained to within 2.5% with a ZSR285 2.85V quiescent current of typically 350µA. Output voltage ZSR300 3.0V change, with input voltage and load current, is much ZSR330 3.3V lower than competitive devices. The ZSR devices are ZSR400 4.0V completely stable with no external components.

Maximum power dissipation, for the SOT223 and SO8 packages, is calculated assuming that the device is mounted on a PCB measuring 2 inches square. 4. The shut down feature of the device operates if its temperature exceeds its design limit as might occur during external faults, short circuits etc. If the regulator is supplied from an inductive source then a large voltage transient, on the regulator input, can result should the shut down circuit operate. It is advised that a capacitor (1µF or greater) should be applied across the regulator input to ensure that the maximum voltage rating of the device is not exceeded under shutdown conditions. 1. The maximum operating input voltage and output current of the device will be governed by the maximum power dissipation of the selected package. Maximum package power dissipation is specified at 25 °C and must be linearly derated to zero at Tamb=125°C. 2. The following data represents pulse test conditions with junction temperatures as indicated at the initiation of the test. Continuous operation of the devices with the stated conditions might exceed the power dissipation limits of the chosen package.
